ASUNburnt brightly in the clear sky above the wasteland, highlighting the arid earth and bare rocky hills. A coarse red dust covered much of the land, choking the dry soil. When strong winds blew, the dust rose in sheets, making breathing almost impossible. At such times I pulled on one of Harkat's spare masks it blocked out the worst of the grainy particles and the two of us sought shelter and waited for calm to descend.

It had been two weeks roughly since Mr Tiny brought us to this desolate land and abandoned us. Two weeks crossing barren valleys and dead hills, where nothing lived except a few hardy lizards and insects, which we caught and ate whenever we could. They tasted disgusting but you can't be choosy if you're stranded in a desert without food or water.

Water was our main concern. Walking in the heat and dust was thirsty work, but water was in scarce supply and we didn't have any canteens to store it in when we found the occasional pool. We'd fashioned primitive containers from the skins of lizards, but they didn't hold much. We had to drink sparingly.

Harkat was angry with me for disobeying his wishes he ranted at me nonstop for a few days but his temper gradually abated. Although he hadn't thanked me for choosing to accompany him on his quest, I knew he was secretly grateful.

A fortnight earlier, Mr Tiny followed us through the doorway, which collapsed into dust after him. There'd been a brief moment of disorientation when I stepped through, a grey cloud obscuring my vision. As the cloud cleared, I saw that I was standing in a round, shallow, lifeless valley and although it had been day when I stepped through the doorway, here it was night, albeit an uncommonly clear night, bright with a full moon and a sky filled with twinkling star clusters.
